| Notes | When a species moves into an area it has not previously inhabited, how does it recognize and defend itself from predators? This article explores this question using the highly edible purple varnish clam, native to Japan, which is now found in most Oregon estuaries. They tested native Japanese clams, along with clams that had been introduced into British Columbia and Oregon, for their responses to predators, especially Dungeness crabs. The clams that were acclimated to North America responded to the presence of Dungeness crabs by digging deeper burrows, while the Japanese clams did not seem to recognize the crabs as predators. This suggests that the defensive burrowing was not a strategy used by the initial invading population. “Nevertheless, this mechanism may be important for the initial establishment of some species and population growth and expansion for other species once they learn the cues of local predators” (from the Abstract). |
